--- Comment #28 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Wilhelm M from comment #26) > As you can see in my opening bug report, there is no nullptr reference nor > dereferencing a pointer with value 0. Yes but as I mentioned by the time the warning happens, the IR has lost information if the constant came from a null pointer or from some other constant that the user used. So a heuristic needs to be used and the idea was it would be the lower bytes by default and that the lower bytes would be defined by a "page size" and that is how the naming of the option happened.
